Yes, Huckabee is the Republican to watch
agreed. Let's face it, most of the Republican money is still on the sidelines. Huckabee's biggest problem has been that he is from Ark (I had a hard problem with that one). Social Conservatives don't trust Rudy, Romney, McCain, or Thompson. As Thompson continues to fade, Huckabee's support will pick up.
Huckabee is still very unknown, so he will be the last to be "examined" by GOP primary voters. But social conservatives will be comfortable with him, and he has enough fresh ideas in medical care and education to offer a change in course.
